PAPER-HANGING MACHINE.

SPECIFICATION forming part of Letters Patent No. 453,174, dated May 26,1891.

Application filed October 28, 1890.

ToaZZ whom it may concern:

Be it known that I, ADAM H. LOHLKER, a citizen of the United States,residing at St. Paul, in the county of Ramsey and State of Minnesota,have invented certain new and useful Improvements in Paper-HangingMachines; and I do declare the following to be a full, clear, and exactdescription of the in vention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being badto the accompanying drawings, and to figures of reference markedthereon, which form a part of this specification.

This invention relates to an improved form of paper-hanging machine; andthe invention 7 consists in the construction and. arrangement of thevarious parts whereby the entire work necessary to be performed inhanging wallpaper and preparing the same for hanging such as trimmingthe edges, cutting to the proper width in case of the necessity of usinga narrow strip, pasting, placing upon the wall, smoothing after beingplaced in posit-ion, and cutting off at the proper lengthmay beaccomplished by a single piece of apparatus and without the necessity ofemploying skilled workmen,

The object of the invention is to furnish a device or combination ofdevices which shall perform most of the operations necessary by simplyturning a crank and in which the portions of the work not so performedare accomplished by movements requiring little skill and in much lesstime than in the ordinary manner. Theinvention will be more fullydescribed by reference to the accompanying drawings, in which- Figure 1represents a view in perspective of my improved paper-hanging machine;Fig. 2, a section of the principal operative parts, and Fig. 3 a similarview of a modified form of the same. Fig. 4 is a front view of rollersand table.

E The standard consists of an upright framework 1, carrying anextensible part 2, which may be raised or lowered upon the part 1 in anydesired manner to adapt the apparatus for use upon walls of differentheight. The two parts of the frame may be so arranged as to slide withreference to each other, as by Serial No 869,638. (No model.)

means of ways formed upon the part 1 fitting in corresponding grooves inthe other section 2.

At any convenient height upon the standard 1 is located the paste-box 3,having bearings, formed in the ends thereof, supporting a roller 4, uponwhich the paper is wound. At the other side of the box and parallel tothe paper-roller is similarly mounted a pastebrush 5, operated by meansof a belt 6 from the drive-shaft 7, to which an operating-crank S isattached. The paper is passed from the roll over the paste-brush to thepaste-distributer, which-consists of a vertical table 9, behind whichthe paper is passed, and so located that the lower edge of the samepresses the paper closely against the brush. Behind this vertical tableare located one or more brushes 10, between which and the table thepaper passes, its pasted side being toward the brush or brushes whichpress the paper, spreading the paste evenly over the same.

At the top of the distributor is located the cutting-table 11, overwhich the paper passes between two rollers 12 12, one being thedriveroller, by the turning of which the whole apparatus isoperated.These rollers are provided at each end with circular cutters 13, fittingtogether in shear fashion and adj ustable upon the shafts, the rollersbeing a snug fit, and consequently movable longitudinally thereupon.These cutters are placed at a distance apart suited to the width of thepaper, and when properly adjusted will trim both edges of the paper asthe same passes between them, the adj ustability above referred to beingfor the purpose of changing to suit different widths of paper. For thepurpose, also, of enabling narrow strips to be cut as is oftennecessary, the table 11 is provided with a series of narrow slots 14,running in the direction of the length of the paper, into any one ofwhich the point of a knife may be inserted to cut the same as it isdrawn along by the turning of the rollers. These slots may be arrangedat a distance of about half an inch apart across the table.

To the drive-shaft is also belted or other- 16, which moves the endlesscarrier-belt 17,

extending to the top and front of the upper wise operatively connected aroller or shaft frame, being mounted and supported thereon at convenientpoints by means of suitable rollers. This belt is preferably of canvasor similar material, and of a width about equal -to or a little greaterthan that of the paper. The end of the paper is attached to thecarrier-belt by means of the device hereinafter described or otherwise,and carried along to the top and front of the frame, from which pointthe carrier returns and the paper falls of its own weight. or may beassisted by the release of the means by which it was attached thereto.The crank is turned until the end of the paper has fallen to the properpoint, when the operator presses the end. against the wall at the upperedge of the base-board, at the same time matching the figure, if any,with the paper previously hung. \Vhen at tached at this point the,smoothing device is operated. This is as follows: At the top and frontedge of the upper section of the frame is mounted a spring-roller 18,similar in all respects to an ordinary window-shade spring-roller. Tothis roller is attached, by means of a wide band 19 of a lengthsuiticient to reach to the fioor or base of the frame, a slidingcarriage mounted upon ways or tracks upon the frame, so as to slidevertically thereon, and carrying a brush 21 of a width equal to or alittle greater than that of the paper. The carriage carrying the brushis drawn down to the base of the frame and fastened until ready foruse-that is, until the paper has been fitted and fastened to the wall atthe bottom. It is then released, and the spring in the roller 18 causesit to fly rapidly to the top, pressing the paper closely and smoothly tothe wall for the whole dis tance. The paper is cut at the top of thewall automatically by means of a horizontal knife 22, pivotally hungacross the front of the upper frame and outside of the paper. The edgeof this knife turns inwardly toward the paper and has a saw-tooth orserrated edge against which the paper is pressed by the face of thebrush 21 as it reaches the top, thereby cutting it at the proper pointand allowing the brush to press it closely to the wall. The operation isnow completed, and the apparatus is made ready for hanging the nextwidth by being moved along to the next space by means of suitablerollers or casters upon which it is mounted.

By the use of this apparatus both edges of the paper are trimmed,thereby insuring a uniform width and avoiding the necessity ofoverlapping one width upon the next. The paper is evenly pasted andevenly and quickly laid upon the wall, and the device can be operated bya boy as well as by a skilled workman. The end of the paper, whenbeginning, upon a new roll, may be attached to the carrier-belt, so asto be moved along therewith, by means of a pocket 23 formed therein,into which the end of the paper is inserted and held therein by means ofarod or other weight.

When the belt reaches the point at which it begins to descend, the roddrops, releasing the paper and allowing it to hang by its own weight.

In Fig. 3 is shown a modification of the apparatus in which thepaste-box is located nearly level with the cutting-rollers, and thedistributing-brush 10 is located vertically on the rear of the box insuch a position that the paper is drawn over the same. The operation isin all respects similar to that above described.

I claim as my invention-- I. In a machine of the class described, thecombination of the paper-rollholder, the pastebox having a revolvingbrush therein in position to bear against the back of the paper, therollers provided with circular shear-cutters at each end, between whichthe paper is adapted to pass, means for operating simultaneously thesaid rollers and paste-brush, and a slotted table over which said paperpasses to enter between said rollers, substantially as and for thepurpose herein specified.
